Paper Abstract

Amplification of high-power ultrashort pulses in gas-discharge amplifiers is investigated theoretically. The most essential features of amplification in this case are connected with an electron density wave (EDW) generated by laser pulse in gain medium due to the avalanche ionization. Traveling with amplified pulse, EDW results in the pulse amplitude and phase modulation. Also, it determines the ultimate pulse parameters (energy, peak intensity, duration) and features of pulse evolution in long amplifier. The laser operation with a variety of CO2 multi-isotope mixtures is investigated also. Such operation enables amplification of laser pulses with duration down to 100 fs. Moreover, in a particular spectral domain, the picosecond pulse amplification at reduced gas pressure becomes possible.
